Applications & Selection Guide
Carbon steel butt-weld pipe caps to EN 10253 / ASME B16.9 — ellipsoidal end closures with a bevelled edge welded directly onto the pipe end for a permanent, pressure-tight termination.
Caps terminate headers and future-expansion stubs, close vessels and pig launchers, and blank lines during hydrostatic testing. Unlike a blind flange, a welded cap is permanent and gasket-free — choose it where the line will not need reopening; choose a blind flange where periodic access is required. Available ODs are listed above.
Quoted and sold per piece. State the OD, quantity, and delivery country in your quote request; caps ship together with our elbows, tees, and reducers in consolidated fittings orders.
